Obviously, it’s still possible to lose weight on any diet – just eat fewer calories than you burn, right? The problem with this simplistic advice is that it ignores the elephant in the room: Hunger. Most people don’t like to “just eat less”, i.e. being hungry forever. That’s dieting for masochists. Sooner or later, a normal person will give up and eat, hence the prevalence of “yo-yo dieting”.
But people who started following the keto diet noticed weight loss for a few reasons: When you eat carbs, your body retains fluid in order to store carbs for energy (you know, in case it needs it). But when you’re not having much in the carb department, you lose this water weight, says Warren. Also, it's easy to go overboard on carbohydrates—but if you're loading up on fat, it may help curb cravings since it keeps you satisfied.
The ketogenic diet is a mainstream dietary therapy that was developed to reproduce the success and remove the limitations of the non-mainstream use of fasting to treat epilepsy.[Note 2] Although popular in the 1920s and 30s, it was largely abandoned in favour of new anticonvulsant drugs. Most individuals with epilepsy can successfully control their seizures with medication. However, 20–30% fail to achieve such control despite trying a number of different drugs. For this group, and for children in particular, the diet has once again found a role in epilepsy management.
The website LiveItBeautiful.com states, “The military diet plan is designed to help you lose weight in just three days, which can affect some people adversely…. [S]ide effects or health conditions you can experience with the military diet plan include: dehydration, headaches, weakness, irritability, fatigue, muscle loss, and irregular menstruation.”
The Military Diet is a strict, short-term plan that requires drastically reducing your caloric intake. The restrictions work over a three-day period, and then you take four days off from the diet. Some users participate in the Military Diet on an occasional basis, while others might do three days on and four days off for a month at a time. In fact, the Military Diet website touts that people who follow the plan for 30 days could “lose up to 30 lbs,” though registered dietitians strongly advise against doing so. (More on that later.)
According to registered dietitian Andy Yurechko, an outpatient GI dietitian at Augusta University Medical Center in Georgia, the military diet is a low calorie, (only 800-1,200 calories are recommended) a low carbohydrate, moderate protein, and moderate fat regimen type of diet that is observed for three days out of the week. You are restricted to 1,500 calories for the remaining four days of the week, Yurechko explained, and no foods are off limits.
Intermittent fasting has blown up in the past year, but scientists are just starting to figure out how it can help you lose weight. In one study from the University of Illinois at Chicago, researchers compared obese people in a traditional weight loss group and fasting group. For the experiment, the calorie-restricted group simply reduced the amount of calories they ate by 25 percent each day. The fasting group, however, alternated days: they ate 25 percent of the calories they needed one day between 12 and 2 p.m., and then had feast days the next, where they ate 125 percent of their required calories.
When you’re eating the foods that get you there (more on that in a minute), your body can enter a state of ketosis in one to three days, she adds. During the diet, the majority of calories you consume come from fat, with a little protein and very little carbohydrates. Ketosis also happens if you eat a very low-calorie diet — think doctor-supervised, only when medically recommended diets of 600 to 800 total calories.
Boredom is dangerous and so easily leads to weight gain. While free time gets perceived as relaxing, it actually makes me feel anxious, which can lead to bad eating habits. My busiest days are the ones when I tend to focus less on my food and more on what I need to get done. That's why I always try to fill my schedule with things that make me feel productive—so I don’t find myself rummaging through the pantry for a lack of something to do.
